Swamp rains surpass noteworthy mark

Wet season rains have now surpassed 40 inches of rain to the swamp,

As tabulated from May 1st to October 31st (Halloween).

The above rain chart reports annual rainfall for Big Cypress Nat'l Preserve as calculated according to south Florida's water year, i.e. May 1st to April 30th. The chart uses color coding to differentiate between the rainy and non-rainy halves of the water year. The meteorologic wet season is coded blue and the meteorologic dry season is coded yellow. The chart also differentiates between months of the year by alternating light and dark shading.

The long-term wet season average is 43 inches.

This year's bar will easily break that plane by the end of September.

The bigger question is what happens in October.

It has a reputation for being a "make or break" month but unlike reliable core summer rains, i.e. afternoon showers, October also has a reputation for being "hit or miss." Will the tropics deliver, or won't they? Can you see in the graph above how the past two October's have been on the rainier side of the historical average? Compare that to October 2009 and 2010 which managed to produce hardly any rain at all.
